Update to NodeJS 8, Angular 6, electron 2.0.2, RxJS 6.1

[leo6104]

Changes

• Upgrade to angular 6.0.2 (using ng update @angular/cli command two times)
• Remove 'rxjs' blocklist from tslint.json, import all members from 'rxjs'
• Upgrade to Electron 2.0.2 with bigger favicon (512x512)
• Change README.md
• Travis CI runs with NodeJS 8 system. (Angular cli 6 supports only 8.9 >=)
• add lint, e2e, test process to Travis CI
• remove hooks, use fileReplacements logic in angular.json
• Cleanup npm scripts with -- parameter patterns.

Tests

• npm run ng:serve works!
• npm run build works!
• npm run test works!
• Test with windows
• Test with mac

Since Angular 6 supports webpack 4 without node-js built-ins (angular/angular-cli#9827 (comment)), ng serve shows some warning messages.

WARNING in ./node_modules/zone.js/dist/zone-mix.js
Module not found: Error: Can't resolve 'crypto' in '/Users/sangmin/Desktop/Github/angular-electron/node_modules/zone.js/dist'

WARNING in ./node_modules/zone.js/dist/zone-mix.js
Module not found: Error: Can't resolve 'fs' in '/Users/sangmin/Desktop/Github/angular-electron/node_modules/zone.js/dist'

WARNING in ./node_modules/zone.js/dist/zone-mix.js
Module not found: Error: Can't resolve 'timers' in '/Users/sangmin/Desktop/Github/angular-electron/node_modules/zone.js/dist'

But, with electron serving, it works well :)

I am not a PR approver on this project, just a user. I wanted to give this PR a spin since it puts Angular 6 + Electron 2 together. Everything appears to be working with this PR, except that when I ran npm test I got the following error:

angular-electron leifwells$ ng test

Not a lot information or clues to debug on from this error and I expect there is something out of date or missing on my computer, but wanted to mention it here.

@leifwells Nice catch :) I found the root cause is the warning messages i mentioned in above.
The warning messages came from import 'zone.js/dist/zone-mix'; in polyfills.ts.
So, i modify angular.json to use polyfills-test.ts instead of polyfills.ts when karma test run.

Now, added npm run lint/test/e2e process in Travis CI.
Please check @maximegris :)
